Abstract
An assembly includes a medical device having a stent and a prosthetic valve connected to the stent. The prosthetic valve includes valve leaflets. The assembly further includes a buffer piece having a leaflet cover and a removable attaching structure. The leaflet cover protects the valve leaflets and the removable attaching structure removably attaches the buffer piece to the medical device. The buffer piece prevents contact, imprinting, abrasion, and/or damage to the valve leaflets.
